///FLX380 FlexTester3 OTDR with LinkMap

FLX380 FlexTester3 OTDR with LinkMap

The AFL FLX380 FlexTester3 is the world’s smallest, lightest, most complete single mode fiber optic test set. It combines highperformance, multi-wavelength OTDR/PON OTDR, Source, Power Meter, VFL and PON Power Meter in a rugged, hand-held package.

With 42 dB dynamic range, best-in-class event, attenuation, and PON dead zones, LinkMap with pass/fail analysis, macrobend and splitter detection, launch quality check, plus AFL’s unique ServiceSafe® and Wave ID features, the FLX380 FlexTester3 Series offers an unmatched combination of optical test functions, ease-of-use, portability, and value.


Over 1000 OTDR test results (Telcordia SR-4731 .SOR file format) may be saved in the FLX380’s internal 4GB memory. Stored OTDR and OPM results may be transferred to PC via Bluetooth or USB. Windows® compatible TRM® 2.0 Test Results Manager software is included for OTDR and Power Meter results viewing, analysis, and professional report generation.

New LinkMap™ Simplifies Network Troubleshooting
Using the FLX380’s new LinkMap capability, even novice users can troubleshoot optical networks like a pro! LinkMap interprets the tested network and presents an icon-based view of network elements clearly identifying fiber start, end, connectors, splices, splitters, and macrobends. Loss and reflectance of network elements is compared to user-settable pass/fail thresholds and displayed with clear pass/fail indications. Users can instantly toggle between LinkMap and Trace view at the press of a button.

With launch quality check, integrated macrobend and splitter event detection, FLX380 OTDRs offer even greater ease-of-use. FlexTester3 OTDRs also provide a Link Summary showing end-to-end link length, loss, loss/distance and ORL.

ServiceSafe® Testing on Live PONs
In FTTx PONs, troubleshooting a faulty fiber connection from one out-of-service subscriber’s location using a 1310/1550 nm OTDR could disrupt service to active subscribers. AFL’s ServiceSafe feature alerts the OTDR user to the presence of live traffic and prevents the OTDR from initiating service-disrupting tests at 1310/1550 nm. FLX380-303 and -304 models measure downstream power levels at 1490 nm and/or 1550 nm, and allow the user to initiate an OTDR test using a non-disruptive 1625 nm or 1650 nm OTDR wavelength. Using AFL-patented technology (US patent 8,411,259), live PON OTDR testing is performed through the same optical port used for 1310/1550 nm OTDR testing, eliminating unnecessary connector wear and tear and shortening test time.

Fast, error-free Loss Tests using Wave ID
All FLX380s integrate an Optical Laser Source (OLS) and Optical Power Meter (OPM) supporting AFL’s unique Wave ID capability. With Wave ID, the OPM automatically synchronizes to a single or multi-wavelength Wave ID optical signal sent by another FLX380, OFL280, or AFL hand-held OLS. The OPM automatically determines which wavelengths are sent and measures power and loss at each wavelength, saving significant test time and eliminating setup errors. The integrated OLS and OPM also generate and detect fiber-identifying tones to enable positive fiber identification before disconnecting fibers during maintenance.

OPM results may be saved using the same file-naming convention applied to OTDR results. Saved OPM results may be recalled and viewed or uploaded to TRM for report generation.

Create Professional Test Reports using TRM® 2.0
Saved OTDR and OPM results may be uploaded to PC, viewed and analyzed using the included TRM 2.0 Test Results Manager software. With TRM’s report generation wizard, users can easily create professional, customized fiber acceptance test reports.
